Dear Fellow Photographers,
Recently, I watched Creating Timelapse Video with Richard Harrington on Lynda.com. Today I decided to test out what I had learned by shooting freeway traffic on a bright sunny day in downtown Seattle.
One of Richard Harrington's tips is to disengage (twist the lens slightly) to keep the aperture from changing slightly for every shot taken during a time-lapse. So I tested it out only to find my images overexposed. Is it because I should only disengage the lens for long exposures time-lapses at night? Or is it because I didn't cover the viewfinder? Or ..... I dunno.
Another tip is to enable Mirror Lock-up. I got a bit paranoid from not hearing the shutter click and immediately turned it off. Any feedback or help is greatly appreciated...
Here are my notes so far from the course:
Time-lapse Camera Configurations for Canon 5D Mark III
• Turn off Auto Lighting Optimizer for Manual mode (if shooting in JPEG) & Noise Reduction to eliminate camera post-processing.
• Engage Mirror Lock-Up to reduce Camera Vibration from the movement of the Mirror.
• Set Custom White Balance (Sun, Shade, Cloudy) to prevent camera from changing Color Temperature in the middle of the sequence.
• Set Camera Lens to Manual after framing and focusing the shot.
• Lock Aperture by disengaging Lens from Camera Body with a slight twist of the lens. All settings must be set before this step.
Any suggestions or thoughts...I did DO a timelapse without disengaging the Lens. I haven't run it through post processing yet. The images are exposed just fine.
One last question: Any suggestions on finding a good, cheap ND filter for a 16-35mm lens? I wanted to drag my shutter speed today but was unable too given the bright sunny conditions. I do have a polarized filter, but don't like the effect of having the sky darker in some areas than others...
Sorry for the long winded post...I am a bit excited about this "Creative Endeavor."
